Experiment and numerical simulations of a slug rivet installation process based on different modeling methods.

Slug rivet interference-fit riveting is one of the advanced connection technologies, which has been widely applied in aerospace manufacture. In the fields of residual stress analysis, structural deformation analysis, load transfer mechanism analysis, and the assessment of the effects of process parameters on riveting quality, study accuracy needs increasingly accurate and comprehensive models. Since the simulation of riveting process is a particularly time-consuming case. The aim of this paper is to develop some appropriate FE models for the special applications with a compromise between model size, calculation time, and simulation precision. Different types of FE models have been established based on force-controlled approach and displacement-controlled approach. The comparison between different FE models is satisfactory in terms of riveting process and riveting quality control criterion. The study significantly deepens the comprehension of the slug rivet installation process. Subsequent research can select an appropriate model according to its special target. The study will pave the way for further investigations. [ABSTRACT FROM AUTHOR]
